It seems as though Lee Jong Suk has fallen victim to impersonation.

Recently, Lee Jong Suk left a warning to his Facebook impersonator via me2day, writing, "What's this... I don't use Facebook! If I catch you, you're dead!" He then added, "Tune into tonight's broadcast," telling fans to make sure to watch his drama, 'School 2013'.

Accompanied with the post was the photo above in which the actor is seen smiling brightly for the camera while dressed in his school uniform for his role.

Concerned fans responded, "People need to stop impersonating others", "If the impersonator gets caught by me, that person is dead", "Be careful", and more.
